Export vorticity as a vector field from Ansys Fluent

[JMA337]

Hi,

I am running simulations in batch. I export the vorticity field for post-processing, but vorticity is not saved as a vector field, like velocity, but as a scalar field. I want to save it as a vector field

The command I use to export the data file is: 

/file/export/ensight-gold "./export/ensight/ensght" mean-y-velocity mean-y-velocity-dataset mean-z-velocity  mean-x-vorticity-dataset mean-z-velocity-dataset mean-wall-shear mean-y-vorticity-dataset mean-z-vorticity-dataset mean-x-velocity-dataset rmse-x-velocity-dataset rmse-y-velocity-dataset rmse-z-velocity-dataset x-velocity y-velocity  () yes * () () no

 

But from the .encas file export, it is celar velocity is the only vector field saved.

FORMAT
type:  ensight gold
GEOMETRY
model: "ensght.geo"
VARIABLE
scalar per node: mean_y_velocity                                  "ensght.scl9"

scalar per node: mean_x_vorticity_dataset                         "ensght.scl13"

scalar per node: mean_y_vorticity_dataset                         "ensght.scl16"
scalar per node: mean_z_vorticity_dataset                         "ensght.scl17"
vector per node: velocity                                         "ensght.vel"
SCRIPTS
metadata: "ensght.xml"

Any suggestions?

Thank you

Hello,

You may not get the vorticity vector transferred from Fluent to EnSight. You can use EnSight's calculator to compute the Vorticity.

You may refer to EnSight help document below for further details.

To export the vorticity field as a vector field in Fluent, you need to ensure that you are selecting the correct components of the vorticity vector during the export process. The command you are using list the vorticity components as separate datasets (e.g., mean-x-vorticity-dataset, mean-y-vorticity-dataset, mean-z-vorticity-dataset). To save them as a vector field, you should group these components together in the export command.
